Hello ouazzar; PCS 7 is a complex set tof hardware and software (including Step 7 and WinCC) than is used to control large processes and plants, much as DCS from other manufacturers are used. Software (programming, controlling, batching, alarming...) and hardware (essentially S7-400 PLCs, redundant or not, and PC stations) are all linked into a working set of components that is more integrated than Step 7 and WinCC can be in your regular programming environment. One example: You program a standard block to control a motor starter ( in CFClanguage) which includes certain alarms specific to this block (Failed to start, Failed to stop...). You program these blocks in Step 7, on a ES (engineering station). You set up an instance of this block for a specific motor and include it in a runtimeSFC (graphic sequence program) and then compile it. Once compiled and sent to the OS (operating stations) where WinCC is installed, the alarms programmed in CFC appear in your graphic pages dedicated to that motor, without extra intervention. And the Alarms database, onlinebanner and acknowledgement sequence are all already defined for these alarms. Of course this is not easily achieved, and there is a great learning curve even for one versed in Step 7 + WinCC programming before he masters PCS 7. If you look at the threads in the conference PCS 7 in the forum, you will habve an idea of the complexity involved. You can also have a look at what is included in PCS 7 on the pages of the Industry Mall: https://eb.automation.siemens.com/goos/catalog/Pages/ProductData.aspx?catalogRegion=WW&language=en&nodeid=5309999&tree=CatalogTree®ionUrl=/#topAnch&activetab=product& Hope this helps, Daniel Chartier |
